If you're in the process of setting up or expanding a private clinic in the UK, at some point you'll need to decide how your team will supply medicines to patients. That decision usually comes down to two options: a Patient Group Direction (PGD) or independent prescribing.
On the surface, both enable a healthcare professional to provide medication to their patients. But in practice, they work very differently, and choosing the wrong model for your clinic's needs can create compliance challenges, limit your services, or leave your team operating outside their legal remit.
This guide cuts through the confusion and gives you a clear, practical comparison, so you can make the right call for your clinic.
What is a Patient Group Direction (PGD)?
A PGD is a written instruction that allows specific registered health professionals, such as pharmacists, nurses, or paramedics, to supply or administer a defined medicine to a group of patients with an identified clinical condition, without needing a prescription for each individual.
It is important to be clear about what a PGD is not. As the NICE Guideline MPG2 explicitly states, using a PGD is not a form of prescribing. The clinician operating under a PGD is working within a pre-authorised protocol. They are not making an independent clinical prescribing decision.
PGDs work well in situations where the clinical pathway is highly predictable and standardised. Think vaccination clinics, emergency contraception services, or UTI treatment in otherwise healthy adults. The consultation follows a structured decision tree, and if the patient fits the criteria, the medicine is supplied accordingly.
However, PGDs come with real constraints that clinic owners often underestimate:
- They can only be used for medicines with a UK marketing authorisation.
- They cannot be used for unlicensed medicines, most controlled drugs, or abortifacients.
- They must be developed through a multidisciplinary process, formally authorised, reviewed, and have an expiry date of no more than three years.
- NICE guidance is clear that PGDs should only be used where no other suitable mechanism exists, and should be reserved for situations where there is a clear benefit to patient care without compromising safety.
For multi-site clinics, developing and maintaining compliant PGDs across multiple services is not a small administrative undertaking. If you are running a growing organisation with several practitioners, that overhead can add up quickly.
What is independent prescribing?
Independent prescribing means a practitioner who is registered and annotated as an independent prescriber, typically a nurse prescriber (NMC) or pharmacist prescriber (GPhC), takes full clinical responsibility for assessing a patient, reaching a diagnosis, and making prescribing decisions, all within their scope of competence.
Unlike a PGD, an independent prescriber can prescribe any medicine for any medical condition within their clinical competence. That includes off-label medicines and, except for a small number of controlled drugs, most of the British National Formulary. This flexibility is significant.
Independent prescribing is the model that most closely resembles how a doctor prescribes. The prescriber sees the patient, assesses them as an individual, exercises clinical judgement, and issues a prescription tailored to that person's specific circumstances.
This individual, patient-specific approach is, according to NICE and the NHS Specialist Pharmacy Service, the preferred way for patients to receive medicines. NICE MPG2 explicitly states that clinics should provide the majority of clinical care on an individual, patient-specific basis, and that PGDs should be reserved for limited situations.
The core differences at a glance
| Feature | PGD | Independent prescribing |
|---|---|---|
| Form of prescribing | No | Yes |
| Clinical judgement required | Restricted to protocol | Full clinical autonomy |
| Medicines available | Limited, licensed only | Full BNF, including off-label |
| Controlled drugs | Severely restricted | Most schedules permitted |
| Long-term condition management | Not appropriate | Appropriate |
| Development burden | High (multidisciplinary, expiry dates) | Lower once qualified |
| Staff qualification | Registered professional authorised under PGD | IP annotation with NMC or GPhC |
| Best suited for | High-volume, predictable clinical scenarios | Complex, individual-focused consultations |
When a PGD makes sense for your clinic
PGDs genuinely have their place. If your clinic runs a high-throughput, protocol-driven service where the patient group is clearly defined and presentations are predictable, a PGD can allow non-prescribing staff to operate safely and efficiently.
Examples where PGDs work well:
Travel health clinics. Administering yellow fever, hepatitis A, or typhoid vaccines to adults travelling abroad fits the PGD model well. The clinical scenario is routine, the eligible patient group is clearly defined, and exclusion criteria can be set out in the direction.
Sexual health services. Emergency contraception and certain STI treatments lend themselves to PGD delivery, particularly in high-volume community services.
Minor ailment services. A UTI treatment service in a community pharmacy, for example, where a pharmacist works through a structured clinical decision tree, is a typical and appropriate use of a PGD.
If your team currently uses a platform like Scripter's PGD consultation flows, you will already know how a well-structured digital PGD can guide a clinician through the decision tree consistently, reduce documentation errors, and generate GP notification letters automatically.
When independent prescribing is the right model
For most private clinics offering a broad range of clinical services, independent prescribing will be the more appropriate long-term model. Here is why.
Greater clinical flexibility. If a patient presents with something that does not fit neatly inside a PGD protocol, a non-prescribing clinician is stuck. They either seek prescriber support or cannot help the patient at all. An independent prescriber can assess and manage that patient directly.
Patient confidence and professional credibility. There is a meaningful difference in how patients perceive a consultation led by a practitioner who is prescribing independently, compared with one who is working through a checklist. Independent prescribers take accountability for the full clinical encounter.
No protocol expiry problem. PGDs need to be reviewed and re-authorised every three years, with a multidisciplinary sign-off process. For independent prescribers, clinical practice does not expire. Continuing professional development and annual revalidation keep practice current, but there is no bureaucratic re-authorisation cycle for every medicine type you offer.
Long-term condition management. NICE guidance is explicit that PGDs should not be used for managing long-term conditions such as hypertension or diabetes. If your clinic offers weight management, hormone therapy, or ongoing chronic condition support, independent prescribing is the only appropriate route.
Overseas and complex patients. As noted in clinical practice guides, an emergency supply of prescription-only medicines cannot be made to overseas patients via a PGD. An independent prescriber can issue a private prescription in those circumstances.
For clinics using Scripter's clinical template system, independent prescribers benefit from consultation templates built around NICE guidelines that guide thorough, structured assessments without limiting the prescriber's clinical autonomy. It feels like a clinical mentor in the room, not a rigid tick-box form.
Can you use both in the same clinic?
Yes, and many clinics do. There is no reason a clinic cannot have PGDs in place for specific high-volume, protocol-driven services while also employing or contracting independent prescribers for broader clinical work.
In fact, NICE guidance acknowledges that PGDs can serve as an interim option while independent prescribing capacity is being developed. If you are growing a team and do not yet have IP-annotated staff across all roles, a PGD can fill a specific gap in the short term without compromising compliance.
What you should avoid is using PGDs as a substitute for independent prescribing across the board, simply because developing a prescriber pipeline feels like more work. The NHS Specialist Pharmacy Service is clear that PGDs should not be used where a prescriber is, or could be, available to manage care on an individual basis.
The compliance question: what both models demand
Whichever route your clinic takes, compliance documentation matters.
For PGDs, that means:
- Multidisciplinary development and formal authorisation
- Named, trained, authorised professionals listed per PGD
- Review cycles and expiry management
- Governance structures and incident reporting
For independent prescribing, it means:
- Valid NMC or GPhC annotation
- Prescribing only within defined clinical competence
- Consultation records, prescription audit trails, and GP communication
- Regular clinical supervision and CPD
In both cases, good clinical software is not optional; it is how you demonstrate that your practice meets the standard. Structured consultation records, automatic GP notification letters, prescription logs, and audit-ready documentation should be built into how your clinic operates from day one.
So, which should your clinic use?
Here is the honest answer: if your service is narrow, standardised, and high-volume, PGDs are a practical, legal, and well-supported option for certain medicines and patient groups.
But if your clinic is offering a range of clinical services, wants clinical autonomy, needs to manage individual patients with varying presentations, and is planning to grow, independent prescribing is the stronger foundation. It gives your practitioners more flexibility, your patients better care, and your clinic a more robust compliance position for the long term.
Many clinics benefit from having both models running together, with PGDs supporting specific service lines and independent prescribers leading the broader clinical work.
The good news is that the admin burden of either model does not have to be as heavy as it sounds. With the right clinical platform supporting your team, both PGD flows and independent prescribing consultations can be managed efficiently, with proper documentation and governance built in by default.
